Thank you. But I'm afraid I don't understand. The man entry reads:
"--list-only
This option will cause the source files to be listed instead of
transferred. This option is inferred if there is a single source arg and
no destination specified..."
It doesn't say anything about "list remote files". In fact I am
not sure
why it would even contact the remote end. And the behavior does not
change even if no destination is specified.
As far as it ignoring the rest of the command line, note that it does
obey exclusion rules. Symlinks seem to be the only anomaly in its output.
I use --dry-run and --itemize-changes frequently. But I was trying to
find something that would give me a correct list of the candidate source
files but without having to make an expensive connect to the remote
server. Any suggestions?
Thanks,
Michael Hipp

How would it know what needs to be transferred without looking at both source and target? You are correct that it doesn't pay any attention to the target because it doesn't need a target. If the source is remote then it will connect to the remote to do a remote listing and if the source is local then no connection is needed but then neither is rsync. As far as obeying the recursive flag, so does ls. I didn't know it cared about exclude rules but you are right that it does. Guess I never tried. I only ever used it when I was trying to see what was on an rsync server. Anyway, if you want to list all the files and dirs but not symlinks and others in a local tree: find /path -type f -or -type d -print (or -ls) On 09/12/2018 07:53 PM, Michael Hipp via rsync wrote:> Thank you.

My apologies. I'm evidently not communicating very well. I am not asking for a list of what "needs to be transferred", I am looking for a list of those things that are "candidates to transfer". In other words, the source items minus exclusions/filters or anything else that will be ignored (by rsync). Is there any option for rsync that offers such a list? > find /path -type f -or -type d -print (or -ls) This tells me nothing about what *rsync* expects to do. In particular it won't consider rsync's filters/exclusions.
